Cinema plays an important role in the life of any society. Cinema has become a part of the modern way of life.. Its possibilities are unlimited. There are a lot of different kinds of films: thriller films, popular science films, mystery films, documentaries, theatrical films, horror films, and animated cartoons. Besides films may be color or black-and-white, full-length or short, sound or silent, dubbed in mother tongue, three-dimension or wide screen. The 20th century made great changes into the theatre. Cinema, radio, television, video altered the course of the major performing arts and created the new ones. But still there are hundreds of puppet theatres, conservatoires and philharmonics, musical comedy theatres, drama theatres and opera houses where the audiences are excited at the prospect of seeing a play and the actors are most encouraged the warm reception. We go to the theatre to see a play, that is to say, a performance given by actors and actresses. A play of a serious character, dealing with important human problems is called a tragedy. A play of a humorous, lighter character is a comedy (or a farce). Dramatists are called playwrights nowadays and there are no longer such great dramatists as Shakespeare or G.B.Show. But before going to a theatre you should book a ticket at a box-office. The most expensive seats are in the stalls, boxes and dress-circle. The seats in the balcony, pit and the upper circle are less expensive, they are cheap. Then at the entrance to the theatre the attendant tears your theatre ticket in half. He gives you your half back so that you can find your seat by its number. Another attendant shows you to your seat and sells a programme that will tell you which parts the actors are playing and how many acts there are in the play. Then you take your seat and may enjoy the play.
